We are creating a processing page that lists orders, to be validated, then sent to shipping.


We are using two dropdown boxes to control date and status that are passed into a stored procedure that returns data bound to an ej:Grid.  Using forum posts we added a check box and the javascript to have a header check box.  When we change the date dropdown we are getting a 500 error on the checkboxes, (“ServerError.html”). 

Can you point me to the issue, or provide an example of a working grid with a checkbox?

Thanks for your assistance in this issue;


Visual Studio 2015, C#, Syncfusion.EJ, Version=14.2450.0.26, HTML5

Hi Bruce, 

Thanks for your interest in Syncfusion products. 

We analyzed the reported query and suspect that the issue occurs since you are validating the posted data for the page that contains html special characters (<,>,&#). In order to handle this exception, we suggest you to set the validateRequest property of pages as false in web.config file. Please refer to the below code example. 

<system.web> 
    <pages validateRequest="false" /> 
</system.web> 

Please refer to the below online links where this query has been discussed. 



We have created a grid sample with checkbox column and external dropdown list. Upon selecting a value from dropdown, the grid data is bound based on the selected value. 


Regards, 
Ragavee U S.
